<p>

<p>The focus here is put on the IFE system itself. <strong>The objective is to set the boundaries and provide a clear vision of the need</strong>.</p>

<p>The <a href="../In-Flight Entertainment System/7fdc15cd094b4f7cbd926c8d001fb5e7.html#_Q3xl4JTyEeSgObsjQ4XNVQ"><font color="#0066cc">[MCB] All Missions and Capabilities</font></a> diagram&nbsp;shows on the capabilities of the IFE system. Three other diagrams provide interesting entry points to the model:</p>

<ul>
	<li><a href="../In-Flight Entertainment System/e0a467397e504ea6b1980e5efb9ce68f.html#_LzrP8LclEd6PZMYM-Vvo5g"><font color="#0066cc">[SC] System Actors</font></a>&nbsp;lists all the Actors (the aircraft is considered as an actor)</li>
	<li><a href="../In-Flight Entertainment System/411a501a55224fca8b18edbeecb501a1.html#_gaN78KyfEeSJ1PX7slxG4w"><font color="#0066cc">[SDFB] Top Level Functional Overview</font></a>&nbsp;provides a first functional overview of what the actors actually do and what kind of exchanges they have with the IFE system</li>
	<li><a href="../In-Flight Entertainment System/e0a467397e504ea6b1980e5efb9ce68f.html#_xXSwEKv6EeSTJvLsyJitsw"><font color="#0066cc">[SAB] Top Level System Overview</font></a>&nbsp;and its&nbsp;slightly refined version <a href="../In-Flight Entertainment System/e0a467397e504ea6b1980e5efb9ce68f.html#_TGdI0JZDEeS1n7CBuZtEDQ"><font color="#0066cc">[SAB] High Level System Overview</font></a>&nbsp;are <strong>very good entry points to further navigate in the model</strong>.</li>
</ul>

<p>Starting from these high level diagrams,&nbsp;a typical&nbsp;reading path&nbsp;is to dive into the function to visualize their refinement. For example, <a href="../In-Flight Entertainment System/0bfc000cdd3840d39cd32037905a7ab3.html#_Z-lO8LC1EeSAOqSI-4duBg"><font color="#0066cc">[SDFB] [CTX] Run Services</font></a>. And recursively.</p>

<p><strong>Using capabilities as a&nbsp;driver to browse the model is recommended</strong>. Some diagrams are specifically marked for that purpose, for instance <a href="../In-Flight Entertainment System/839ba87384424a01bd1a1f4c3cc6ed52.html#_EsbcMLKzEeSZM9DbsSoyxw"><font color="#0066cc">[SDFB] [CAPABILITY] Provide Video Entertainment Services</font></a>. From this capability covering VOD services to the passengers,&nbsp;browse the functional chains and scenarios to better understand how the capability is fulfilled.</p>

<ul>
	<li>Functional chains: <a href="../In-Flight Entertainment System/e00b45ce330b4b19ac6707095a77f8c0.html#_MOb7kJjJEeSFKIU85IonOQ"><font color="#0066cc">[SFCD] Start Playing VOD Movie</font></a>, <a href="../In-Flight Entertainment System/5ecacd765aa14a9f91f5e00bad983206.html#_m1AKgJjJEeSFKIU85IonOQ"><font color="#0066cc">[SFCD] Resume VOD Movie</font></a></li>
	<li>Scenarios: <a href="../In-Flight Entertainment System/58d8d80a34ab4e60aee2fb8eb885583a.html#_CekP8JWHEeSAToX6gykiew"><font color="#0066cc">[ES] Start VOD Service</font></a>, <a href="../In-Flight Entertainment System/2d18447b6c5a45f78149245290242bab.html#_bkAKcLD-EeSk6sURco8jXw"><font color="#0066cc">[ES] Start Playing VOD Movie</font></a></li>
</ul>

<p>Check the global mode machine of the system with <a href="../In-Flight Entertainment System/1ccc81051b794f8a95e0234f4f4bad6d.html#_ZlrrsPhmEeyYD7A3qrV3tA">[MSM] IFE Operating Modes</a>. Among others, this mode machine is intended to specify under which operational conditions the IFE system is running. Another Mode machine is specifically modelled for what will become the Seat TV: <a href="../In-Flight Entertainment System/f46bd421a0394f23aa32149849966070.html#_ZHdlAPhuEeyYD7A3qrV3tA">[MSM] Seat TV - Movie Player Modes</a></p>
